Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aeration tank for industrial sewage treatment. Background Art

[0002] Sewage treatment is the process of purifying sewage in order to make it meet the water quality requirements for discharge into a certain water body or reuse. This process is widely used in many fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, etc., and is increasingly integrated into daily life. Aeration tanks are required for sewage treatment.

[0003] For example, an aeration tank for sewage treatment disclosed in Chinese patent CN220467738U is provided with an equipment body. When in use, a slide groove, a slider and a top plate are provided to limit the top plate to prevent the top plate from shifting when moving left and right. The top plate can be moved left and right by providing a gear, a rotating shaft and a first motor. When not in use, the protective box is covered to prevent sludge from invading. When operation is in progress, a push plate, an electric telescopic rod and a second motor are provided. When sludge invades the protective box and settles to the bottom, the second motor drives the electric telescopic rod to move the top plate left and right. The retraction rod causes one side of the push plate box to move, so that the sludge can be pushed out. By setting a limit groove, a limit block, a return spring, a slide rod and a box door, the limit block is pushed by the push plate, so that the slide rod fixedly connected to the limit block moves forward together, and the slide rod passes through the protective box to push the box door outward. The box door is opened to facilitate the discharge of sludge. When the push plate moves backward, the elastic force of the return spring drives the limit block and the slide rod to return to their original position. When the protective box is retracted, the box door is closed to prevent sludge from intruding. It can clean while reducing the generation of sludge, effectively enhancing the practicability of the device.

[0004] Although this structure can clean the sludge, the aeration mechanism and the sludge cleaning mechanism are fixed in position, which makes it impossible for the aeration mechanism to aerate the bottom of the pool, resulting in poor sewage treatment effect. Therefore, we propose an aeration tank for industrial sewage treatment that can evenly aerate the sewage inside the aeration tank to improve the sewage treatment effect. Utility Model Content

[0005] The purpose of the utility model is to provide an aeration tank for industrial sewage treatment to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aeration tank for industrial sewage treatment, comprising an aeration tank body, a water inlet is provided on the outer wall of the aeration tank body, a water outlet is provided on the side of the aeration tank body away from the water inlet, a sewage outlet is provided on the side wall of the aeration tank body, and a processing component is arranged inside the aeration tank body, the processing component includes an aeration component arranged inside the aeration tank body, and a cleaning component is arranged below the aeration component.

[0008] Preferably, the cleaning assembly includes a mounting frame fixedly mounted on the outer wall of the aeration tank body, a telescopic rod fixedly mounted on the bottom of the mounting frame, a push block fixedly mounted on the end of the telescopic rod, a limiting groove is provided on the outer wall of the push block, a limiting block is slidably arranged inside the limiting groove, a spring is fixedly mounted on the top surface of the limiting block, and a scraper is fixedly mounted on the outer wall of the limiting block.

[0009] Preferably, the hose is made of soft rubber, and one end of the hose away from the aeration pipe is connected to the outer wall of the sleeve. Under the restriction of the hose, the aeration box can supply air to the inside of the aeration pipe to stir and aerate the sewage.

[0010] Preferably, the outer wall of the sleeve is rotatably connected to the inside of the transverse plate. There are two sleeves, which are symmetrically distributed about the center line of the transverse plate. The two sleeves rotate in opposite directions, which can mix the sewage inside the aeration tank body in a positive and negative direction to improve its treatment effect.

[0011] Preferably, there are eight aeration pipes, which are divided into two groups and distributed in a cross shape with the center of the sleeve circle. Under their restriction, the sewage can be stirred, and the stirring range can be expanded under the action of centrifugal force. Moreover, under the restriction of the two sleeves rotating forward and reverse, the stirring effect can be improved.

[0012] Preferably, one end of the spring is fixedly mounted on the inner wall of the limiting groove, and the end of the spring away from the inner wall of the limiting groove is fixedly mounted on the top surface of the limiting block. Under the action of the spring elasticity, the scraper is tightly attached to the bottom surface of the aeration tank body and the scraper is prevented from being stuck to the sludge with strong adhesion.

[0013] Preferably, there are two push blocks, which are symmetrically distributed about the center line of the inner bottom surface of the aeration tank body. The push blocks are slidably arranged with respect to the inner bottom surface of the aeration tank body. Under the restriction of the push blocks, the scraper can be driven to slide stably.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The aeration tank for industrial sewage treatment is composed of an aeration component. When sewage treatment is required, the sewage inside needs to be fully exposed to oxygen. At this time, the motor is started, and the rotating rod fixed at its output end starts to rotate. The rotating rod drives the sleeve to rotate through the transmission mechanism, and the aeration pipe hingedly connected to the outer wall of the sleeve rotates accordingly. The aeration pipe stirs the sewage inside the aeration tank body to improve its treatment effect. Under the action of centrifugal force, the aeration pipe is swung to expand the stirring range of the aeration pipe, so that the sewage treatment effect is better. At this time, the aeration box is started to pump air into the sleeve through the conveying pipe. The hose is connected to the outer wall of the sleeve, and the hose is connected to the aeration pipe. Under its restriction, air is transmitted to the inside of the aeration pipe to stir the sewage and perform aeration treatment at the same time. When the rotating rod rotates, the driving gear sleeved on its outer wall rotates accordingly, and the driven gear meshing with the driving gear rotates accordingly. The sleeve sleeved inside the driven gear and the sleeve sleeved inside the transmission mechanism rotate in the opposite direction to fully mix and aerate the sewage inside the aeration tank body and improve its treatment effect. The delivery pipe is rotatably connected to the sleeve and connected to allow the sleeve to rotate and transmit air through the aeration box.

[0016] 2. The aeration tank for industrial sewage treatment is composed of a cleaning component as one of its components. When it is necessary to clean the sludge on the bottom surface of the aeration tank body, the telescopic rod is started to push the push block. Due to the sliding arrangement of the limit block fixedly installed at the end of the scraper and the limit groove opened on the outer wall of the push block, under its restriction, the push block drives the scraper to slide on the bottom surface of the aeration tank body to clean the aeration tank body. The sewage outlet is opened to clean the sludge. When encountering some sludge with strong adhesion, the scraper is squeezed, which drives the limit block to slide inside the limit groove and compresses the spring. Reciprocating cleaning measures are taken multiple times to avoid the scraper and sludge from getting stuck. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In this embodiment, when sewage treatment is required, the sewage inside needs to be fully contacted with oxygen. At this time, the motor 512 is started, and the rotating rod 513 fixedly installed at its output end starts to rotate. The rotating rod 513 drives the sleeve 515 to start rotating through the transmission mechanism 514, and the aeration pipe 519 hingedly connected to the outer wall of the sleeve 515 rotates accordingly. The aeration pipe 519 stirs the sewage inside the aeration tank body 1 to improve its treatment effect.

At this time, the aeration box 523 is started to supply air to the inside of the sleeve 515 through the delivery pipe 522. Since the hose 521 and the sleeve 515 are connected, the aeration box 523 is connected to the sleeve 515. 5 is connected to the outer wall of the aeration tank body 1, and the hose 521 is connected to the aeration pipe 519. Under the restriction of the hose 521, air is supplied to the aeration pipe 519 to stir the sewage and perform aeration treatment at the same time. When the rotating rod 513 rotates, the driving gear 516 sleeved on the outer wall thereof rotates accordingly, and the driven gear 517 meshing with the driving gear 516 rotates accordingly. The sleeve 515 sleeved inside the driven gear 517 and the sleeve 515 sleeved inside the transmission mechanism 514 rotate in the opposite direction to fully mix and aerate the sewage inside the aeration tank body 1 to improve its treatment effect.

[0036] Based on Example 1, a preferred embodiment of an aeration tank for industrial wastewater treatment provided by the utility model is as follows Figures 1 to 6As shown: the cleaning component 53 includes a mounting frame 531 fixedly mounted on the outer wall of the aeration tank body 1, a telescopic rod 532 fixedly mounted on the bottom of the mounting frame 531, a push block 533 fixedly mounted on the end of the telescopic rod 532, a limiting groove 534 is provided on the outer wall of the push block 533, a limiting block 535 is slidably arranged inside the limiting groove 534, a spring 536 is fixedly mounted on the top surface of the limiting block 535, and a scraper 537 is fixedly mounted on the outer wall of the limiting block 535.

[0037] In this embodiment, when it is necessary to clean the sludge on the bottom surface of the aeration tank body 1, the telescopic rod 532 is started to push the push block 533. Since the limit block 535 fixedly installed at the end of the scraper 537 is slidably arranged with the limit groove 534 opened on the outer wall of the push block 533, under its restriction, the push block 533 drives the scraper 537 to slide on the bottom surface of the aeration tank body 1 to clean the aeration tank body 1, open the sewage outlet 4, and clean the sludge. When encountering some sludge with strong adhesion, the scraper 537 is squeezed, which drives the limit block 535 to slide inside the limit groove 534 and compresses the spring 536. Reciprocating cleaning measures are taken to avoid the scraper 537 and the sludge from being stuck.

[0038] Among them, one end of the spring 536 is fixedly installed on the inner wall of the limiting groove 534, and the end of the spring 536 away from the inner wall of the limiting groove 534 is fixedly installed on the top surface of the limiting block 535.
